1) Use VNC or something similar to remotely access the PC
2) Setup Resolume on your control PC and your show PC, enable OSC output on the control PC and OSC input on the show PC, make sure the IP addresses are correct, and you should be able to have the show PC do everything the control PC does in Resolume

I just tried out 2) on a couple of my machines, and it took about 30 seconds to set up. Works fine. Works best if you have the same comp loaded on both machines.

Hi all,
I'm asking for the way to remotely controlling the Resolume Arena
My PC will be behind the led display for the connections to the video-proseccors
But the control area and the operators will be far and in the different place

So, I'm asking about the way to controlling the Arena software remotely by laptop over UTP cable

That's what I do most of the time and I extend 4K/30 signals over 300ft of Cat6a copper all the time with no issues at all.

If you go that route, keep in mind that HDBaseT needs its own infrastructure which means it can't be concurrent with an ethernet network on existing infrastructure. Also, it will not go through ethernet routers and switchers. Also, my recommendation to you is to use Cat6a copper cables if you use anything above 100ft.
